nRF52832 - how is the 0.6V reference generated?

[Dave Smith]

I would like to use the A/D converter to monitor the battery voltage and need to know if the 0.6V reference is generated with a bandgap or some sort of divider network.

Thanks,

The internal reference is designed as a stand alone reference. A vdd/4 reference is also selectable.
